Honestly, yeah. After seeing how smoking has ruined my mother, I'm against it. Its not my business if people want to smoke - I won't belittle them for it, and I won't try to preach to them to quit. But it will affect my judgements of them. I don't like it one bit.

For the sake of saying, it looks cool, in fiction. In anime, manga, and other media, it helps bring out a characters traits. I'm fine with that.
